See my posting related to interoperability concerns that don't
necessarily have anything to do with a replicated environment:

http://www.imc.org/ietf-ldup/mail-archive/msg01067.html

The general answer to your question is that not specifying
at least one standards-track cookie format means that
LCUP interoperability will only be achieved if a few
implementers decide to cooperate to make it happen. Even
*if* that happens, it may or may not last beyond
version 1.0 of the implementations themselves...

As a WG Co-Chair, that's a situation I can't justify
letting us get into without some very compelling reasons.

So far, I've heard no arguments that I consider compelling
enough to outweigh the risk to interoperability that
an opaque cookie poses.

I am definitely OK with the approach of specifying a high-level
cookie structure of "<OID>-<payload>" in the LCUP spec itself
and dealing with the issue of publishing one or more OIDs with
associated payload syntaxes that are standards track.

This approach is outlined here:
